Unlocking Galaxy S7 without sim

Per instructions, I've removed the sim card from Galaxy S7 and followed the instructions in the email.  Won't unlock.  However, when looking at the device unlock instructions in the PDF (not unlock instructions in email), it indicates that you should put the sim from new carrier in the phone.  Don't have a new sim.  Planning on taking phone abroad.  How do I insure that it's unlocked?  Thanks.

Put this in the dialer and hit send

#7465625*638*CODE# (CODE is the Unlock Code ATT sent you)

Hello @Kate820,

The only way to confirm this type of device is unlocked would be by inserting a different carriers SIM card in it. We can also confirm if the code you received is correct in our system. I will send you a private message to double check this for you. Please check your Forum's Inbox shortly for this!

Did you get unlock successful?

Try using the dialer code without the code att sent you.

I'm selling my S7 Edge. I received the unlock approval email from AT&T. 

I have removed the existing AT&T SIM card, but I do not have another SIM card to replace it with. How can I ensure that the phone is unlocked for the buyer? Shall I just provide them with the email code and instructions so they can put in their SIM card when they get the phone? I want to make sure the transfer of ownership goes seamlessly.

Read the solution post!

lol... Thanks. 

I think my phone may have already been unlocked by a tech at the store... I removed SIM, restored to factory settings, and get a Welcome screen tutorial that takes me all the way in to where I can see apps, etc. Obviously, no calls or anything can be made since there isn't a SIM, but it doesn't prompt me to put in my ATT provided code. Does this sound like I'm already unlocked and ready to go?

No,  it doesn’t indicate one way or the other.
